4 Claims.

This invention relates to a portable metal vention consists in certainnovel features of construction, combination and arrangement of parts tobe hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had tothe following description and accompanying drawing, in which Figure 1 isa side elevation illustrating a portable rail bending device constructedin accordance with my invention.

Figure 2 is a sectional view taken on the line 2--2 of Figure 1.

Figure 3 is a fragmentary end elevation illustrating the device.

Figure 4 is a fragmentary side elevation illustrating an operating leverand the dog carried thereby. 7

Referring in detail to the drawing, the numeral 1 indicates a frame ofsubstantially U- shape providing parallel spaced arms 2 and a connectingportion in the form of a feed box 3. The free ends of the arms 2 arebent upon themselves to form journals receiving axles 4 on which arejournaled rollers 5. The peripheries of the rollers are concaved andsaid rollers engage one side of a rail, as shown in Figure 2, that is,the rollers 5 are brought in engagement with the tread or ball portionof the rail.

A feed sleeve 6 having feed threads 1 meshes with the feed box 3 andadjacent one end of said sleeve is an annular shoulder 8 abutted by athrust bearing 9. The thrust bearing is mounted on said sleeve and alsomounted on the sleeve is a head Ill. The head If! is free to rotate onthe sleeve and is held against endwisemovement by a fastener ll andalsoabuts the thrust bearing 9. The head If) is provided with a borealigning with the sleeve 6 and through which extends a shaft l2. Theshaft also extends through the feed sleeve 6 and has secured to one enda beveled gear l3. The head ll] includes parallel arms I4 having mountedtherein anti-friction bearings l5 for rotatably supporting a stub shaftNi. Secured on the stub shaft is a beveled gear I! which meshes with thegear l3. A roller I8 is secured on the shaft l6 and is adapted to engagethe opposite side face of the tread of the rail from the side faceengaged by the rollers 5. The periphery of the roller I8 is concaved.Guide elements l9 are formed on the head I0 and contactwith the arms 2,the latter being ofiset, as shown at 20, to position the 5 rollers 5 ina plane with the roller iii.

A ratchet gear 2! is secured on the feed sleeve and a ratchet gear 22 issecured on the shaft 12. The ratchet gears 2i and 22 are closely relatedand separated from one another by a'disc 10 or washer 23. i

A handle head 24 includes bifurcated apertured portions mounted on theratchet gears 2| and 22 and are free to turn thereon. The handle headalso includes a socket to receive the handle 1 25. A spring pressed dog26 is carried by the head toengage either of the ratchet gears and mayhave its position reversed so as to operate either of the ratchet gearsin either direction by an, oscillatory movement of the handle 25. Thedog 26 has a finger piece 21 for disengaging the dog from either of theratchet gears and for reversing the position of the dog. The dog has abeveled end 28 to engage the ratchet gears. The dog 26 when in aretracted position by a pull on the handle 21 will clear the washer 23and thereby permit the lever to be slid endwise of the shaft l2 so thatthe dog can be brought into engagement with either of the ratchet gears.The lever besides being journaled on the ratchet gears may also be slidas described for positioning the dog to engage with the selected ratchetwhen manually released.

In operation, the device is applied to a rail, as shown in Figure 2, andthe roller I8 is adjusted for the proper curvature desired to be made inthe rail by rotating the sleeve 6 through the 0scillatory movement ofthe handle 25. After the proper adjustment of the roller I8 the head 24is adjusted on the ratchet gears to bring the dogs into engagement withthe ratchet gear 2| so that the shaft l2 may be rotated and therebyrotate the roller l8, causing the device to feed along the rail and atthe same time bend the rail.

What is claimed is: V

1. A rail bending device comprising a frame, rollers carried by saidframe to engage one side of a rail, a feed box carried by said frame, afeed sleeve threaded in said feed box, a shaft journaled in said sleeve,a head journaled on said feed sleeve, a roller journaled on said head toengage the opposite side of the rail from the first-named rollers, adrive means connecting the shaft to said second-named roller, and meanswhereby either the sleeve or the shaft may be rotated and in eitherdirection.

2. A rail bending device comprising a frame, rollers carried by saidframe to engage one side of a rail, a feed box carried by said frame, afeed sleeve threaded in said feed box, a shaft journaled in said sleeve,a head journaled on said feed sleeve, a roller journaled on said head toengage the opposite side of the rail from the first-named rollers, adrive means connecting the shaft to said second-named roller, a ratchetgear secured on said sleeve, a second ratchet gear secured on the shaftand closely related to the first ratchet gear, a handle head journaledon said ratchet gears, and adjustable relative thereto, a dog car riedby'said handle head and engageable with either of said ratchet gears andreversible to permit operation of the ratchet gears in either direction,and a handle secured to said handle head.

3. A rail bending device comprising a frame including spaced arms and aconnecting portion for said arms in the form of a feed box, a feedsleeve journaled in said box, a shaft journaled in said feed sleeve, ahead journaled on said sleeve, a thrust bearing between said head andsleeve, said head including arms, anti-friction bearings carried by thelast-named arms, a shaft sleeve journaled in said box, a shaft journaledin said sleeve, a head journaled on said sleeve, a thrust bearingbetween said head and sleeve, said head including arms, anti-frictionbearings carried by the last-named arms, a shaft supported by saidantifriction bearings, gearing connecting said shafts, a roller securedto the second shaft, rollers journaled on the first-named arms and thelatter being offset to position said secondnamed rollers in a plane withthe first-named roller, said rollers having concaved peripheries, meansfor rotating the sleeve and the shaft independently of each other and ineither direction, and guide elements formed on the arms of said head andengaging the arms of said frame.
